In a bowl, cream slightly-softened butter. Combine sugars and vanilla extract. Add baking soda, baking powder, salt. Cream in the eggs until totally combined. If necessary, scrape the bowl to incorporate everything.
Add flour and a smooth seed or nut-butter of your choice. Mix until smooth and totally combined.
Refrigerate the dough for about an hour before preparing balls to bake into cookies.
Roll cookie dough into balls and coat in sugar. You can refrigerate these up until you're ready to bake, (for up to a few days) or freeze the prepared dough for up to a month.
